DESCRIPTION

COKE OVEN BODY INSPECTION AND REPAIR MANAGEMENT SYSTEM AND METHOD

TECHNICAL FIELD

[0001] The present invention relates to coke oven body inspection and repair management system and method.

BACKGROUND ART

[0002] Generally, a coke oven is structured by pairs of coking chambers (referred to as kilns, hereinafter) and combustion chambers. In the coke oven, especially fire bricks used for an inner wall of kiln are exposed to high heat for a long period of time, and further, a lateral pressure load (coking pressure) is applied thereto by a coke pusher at a time of carrying out the coke after the completion of coking (completion of formation of coke). Therefore, in accordance with aging of the coke oven, damage due to aging occurs to respective places in the kiln, such as a brick and the like inside the kiln, in particular. To leave the damages as they are becomes a main cause of various kinds of operation troubles such as poor coking of coal and clogging of kiln. In order to reduce an occurrence rate of these operation troubles and to prolong the life of the coke oven, it becomes necessary to correctly grasp a damage degree of kiln at the present moment through inspection and to conduct appropriate repair of kiln at an appropriate time.

[0003] In general, each coke oven has about several tens to a hundred and several tens of chambers of kilns, and an inspection work for checking a deterioration state of fire bricks in each kiln and the other respective portions of oven body, is conducted on regular basis. The inspection work is conducted through visual observation of a worker, and a result thereof is recorded on an inspection form and used as a criterion for subsequent inspection and repair plans. However, there was a problem that it requires labor and time for the recording, management and inspection of voluminous work records, and thus workability is not good and it is inconvenient. Further, although an inspection date of each kiln is determined by comparing the aforementioned record on the inspection form and a list of inspection cycle, since an amount of information recorded on the inspection form is vast, it is difficult to access the information, resulting in that missed inspection and inspection delay occur, which was a problem. [0004] As a technology to conduct repair by grasping a damage degree of kiln, there has been conventionally disclosed a technology such as image analysis of an inner wall of kiln, current data analysis of a coke pusher and smoke density data analysis. Further, a coke oven has about several tens to a hundred and several tens of chambers of kilns, and a technology to rank these kilns in the order in which they should be repaired, has also been disclosed. For example, Patent Literature 1 discloses a technology in which a kiln to be repaired is recognized and a decision of repair timing is made based on an index obtained by statistically analyzing respective pieces of data (current data in a pusher, image analysis data, smoke density data) relating to the kiln over the past n days.

DESCRIPTION OF EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Fig. 1 shows a schematic explanatory diagram of a coke oven body inspection and repair method utilizing an oven body management server according to the embodiment of the present invention. In Fig. 1, 1 denotes an oven body management server. 2 denotes a PDA terminal and 3 denotes an electronic pen, which are carried by a worker who performs inspection and repair works on site. The PDA terminal 2 functions as an oven body management information input/output unit, and the electronic pen 3 functions as a wall surface management information input unit. 12 denotes a PC (personal computer) terminal capable of communicating with the oven body management server 1, and is a personal terminal of a person involved in the management of operation of each coke oven. Fig. 2 shows a block diagram showing a structure of a coke oven body inspection and repair management system according to the embodiment of the present invention.

[0012] The present invention manages inspection and repair work records of coke oven body from past to present in the oven body management server 1, immediately detects change and condition of the oven body from inspection and repair records for each kiln input, as needed, into the oven body management server 1, and enables the information thereof to be shared among the people involved in the management of operation of each coke oven, including the worker on the site of work.

[0013] The inspection and repair records for each kiln input, as needed, into the oven body management server 1 are recorded by using the PDA terminal 2 and the electronic pen 3 carried by the worker who performs inspection and repair works on site.

[0014] The inspection and repair works of coke oven are conducted on a kiln-by-kiln basis and, for example, 21 portions shown in Fig. 3 are set as targets. As the portions relating to an upper part of the oven, a charging hole frame (1), a charging hole lid (2), a metallic material of flue (3), a tile of oven top (4), a whole ascension pipe (5), a lining of ascension pipe (6), a joint between bricks inside charging hole (7), a bend portion (8), and a tie rod (9) are set as targets. Further, as the portions relating to a lower part of the oven, a door frame (10), a door frame attachment metal fitting (11), a joint outside oven entrance (12), a joint inside oven entrance (13), a protective metallic material of oven entrance (14), an oven lid (15), repair of end plate (16), a coking chamber wall (17), and repair of bellows (18) are set as targets. Further, as the portions relating to a reversing valve and a basement, a platform tile (19), a joint of face wall (20), and a joint surrounding reversing valve (21) are set as targets. The inspection and repair information regarding the coking chamber wall (17) among these target portions is set to be input through handwriting by the electronic pen 3 to manage the information in a manner that it can be grasped as a wall surface image. The inspection and repair information regarding the other 20 portions is set to be input from the screen of the PDA terminal 2.

[0015] As shown in Fig. 2, the oven body management server 1 obtains the information input from the electronic pen 3 as wall surface management information 4, and obtains the information input from the PDA terminal 2 as oven body management information 5. The pieces of information 4, 5 obtained by the oven body management server 1 are stored in an input information storage section la. These pieces of information 4, 5 are processed in an information processor lb, and turned into respective pieces of information of oven body record information 6, periodic inspection guidance information 7, repair kiln guidance information 8, repair life evaluation information 9, and preventive maintenance guidance information 10. The processed respective pieces of information 6 to 10 are stored in a storage section 1c of the oven body management server 1.

[0016] Hereinafter, regarding the wall surface management information 4 and the oven body management information 5 obtained by the oven body management server 1, input units thereof will be explained.

[0017] (Wall surface management information input unit)
The present embodiment utilizes a technology that uses a handwriting input system in which an image input is performed, through handwriting with an electronic pen being a dedicated handwriting input unit, on a dedicated special sheet using Anoto (registered trademark) technology (also referred to as Anoto function), and the handwritten contents are converted into electronic data to be transmitted to a server apparatus.

[0018] Fig. 4 shows a structural example of the electronic pen 3. The electronic pen 3 includes a pen part 14, a pressure sensitive part 15, a camera part 16, a processing part 17, a storage part 18, a transmission part 19 and the like. When a worker performs handwriting input, using the electronic pen 3, on a dedicated paper 13 that is compatible with the electronic pen, the electronic pen 3 can sequentially obtain the contents written in the paper 13.

[0019] The pen part 14 delivers an ink by being moved in a state where a pen tip is pushed against the paper 13 to perform recording on the paper 13. The pressure sensitive part 15 has a piezoelectric element, and is fixed to the pen part 14 to detect a force and a pressure applied to the pen part 14. When the writing is being performed on the paper 13 by the pen part 14, the pen part 14 is pushed against the paper 13, and accordingly, the pressure sensitive part 15 detects that the handwriting input is being performed by the electronic pen 3. The camera part 16 reads, with the use of infrared ray, a dot pattern printed on a surface of the paper 13 at a periphery of a tip portion of the pen part 14.

[0020] There is formed, on the paper 13, a special dot pattern printed by an ink containing carbon. An area in which the dot pattern is formed corresponds to an input area in which a user inputs information by using the electronic pen 3. Respective dots of the dot pattern printed on the input area are two-dimensionally arranged to be printed so that positions thereof can be specified. When the handwriting input is performed on the paper 13 by the electronic pen 3, the pressure sensitive part 15 first detects that the handwriting input is being performed by the electronic pen 3. During when the pressure sensitive part 15 detects that the handwriting input is being performed, the camera part 16 reads the dot pattern on the paper 13. Accordingly, the electronic pen 3 can obtain a trajectory of the tip of the pen part 14 when the handwriting input is being performed, and can obtain the contents written in the paper 13.

[0021] As shown in Fig. 5, in the present embodiment, a wall surface image 52 is printed on the paper 13, and it is designed such that a range of deteriorated portion, a range of repaired portion can be input through handwriting on the wall surface image 52 with the use of the electronic pen 3 (refer to a handwritten portion 51 in Fig. 5). Note that Fig. 5 illustrates the wall surface image 52 in a simple manner, but, actually, a state where fire bricks are laid, sizes of respective portions and the like are described.

[0022] Further, on the paper 13, an inspection/repair specification field 53, a field 54 of target kiln, operation date and name of worker, a field 55 of inspection results of damaged portion (hole in brick, loss of brick, crack of brick, other remarks), a field 56 of repair contents (repair method, removal from oven, repair start and finish time, time at which door is closed, employed material), a field 57 of repair results (range of repair, state of repair, other remarks), and a comment field 58 or the like are printed, and it is designed such that the handwriting input can be performed on each field using the electronic pen 3. The paper 13 in the illustrated example includes fields in which a comment and the like can be freely described using the electronic pen 3 (for instance, the fields 55 to 57, other remarks, and the comment field 58), and fields on which choices are previously printed and checked with the electronic pen 3 (for instance, the inspection/repair specification field 53, the field 55 of inspection results of damaged portion including presence/absence of hole in brick, presence/absence of loss of brick, presence/absence of crack of brick, and the like) .

[0023] The inspection and repair information written in the paper 13 with the electronic pen 3 as described above is converted into electronic data to be turned into the wall surface management information 4. Note that other than the aforementioned pieces of information, a lead line and the like may also be included.

[0024] Further, the electronic pen 3 adds, to the wall surface management information 4 to be converted into electronic data, a damage degree obtained by evaluating the damage degree of wall surface on a six-point scale of 0 point to 5 points. The damage degree is determined based on a damage value automatically calculated, from data input by the electronic pen 3, through a calculation formula of "damage value = (area of unrepaired damaged portion) -T- (total coking chamber area) X 100". In the present embodiment, it is set that "damage value > 9" corresponds to 5 points in the damage degree, "damage value: 7 to 9" corresponds to 4 points in the damage degree, "damage value: 5 to 7" corresponds to 3 points in the damage degree, "damage value: 3 to 5" corresponds to 2 points in the damage degree, "damage value: 1 to 3" corresponds to 1 point in the damage degree, and "damage value: 0 to 1" corresponds to 0 point in the damage degree. For example, it is assumed that an unrepaired damaged portion of a coking chamber having a total area S = 68 m2 is recorded as the handwritten portion 51 shown in Fig. 5. In this case, an area of the damaged portion (S') is automatically calculated from a handwriting of the electronic pen 3, and based on the formula of damage value = S'/S X 100 (%) = 3.2, the damage degree is determined as 2 points. Note that in this case, it is explained that the damage degree is determined by using the electronic pen 3, but, it is also possible to design such that the oven body management server 1 determines the damage degree.

[0025] Note that each of the papers 13 has a paper ID. The electronic pen 3 can obtain the paper ID by reading the dot pattern. Accordingly, even in a case where a postscript is added to the same paper 13, it is possible to easily specify data indicating previously written contents and to easily associate postscript data with the data.

[0026] The processing part 17 performs data compression processing and processing such as addition of ID of the electronic pen 3, on data read by the camera part 16. The storage part 18 stores data on which the processing is performed by the processing part 17. The transmission part 19 transmits information stored in the storage part 18 to the oven body management server 1 by wireless using Bluetooth (registered trademark). Note that the electronic pen 3 has a USB interface (not shown), and can also output data to the outside by wire using a USB cable.

[0027] (Oven body management information input/output unit 2)
Fig. 6 shows a work record input menu screen of a PDA terminal. On the work record input menu screen of the PDA terminal 2, inspection and repair target portions 61 of the respective portions of oven body (other than the coking chamber wall (17)) are displayed in a selectable manner. Further, there are displayed an instruction button 62 that instructs to perform data transfer from the PDA terminal 2 to an external device, an instruction button 63 that instructs to perform data transfer from the external device to the PDA terminal 2, and an end button 64. The worker selects the target portion 61 to call a recording screen (Fig. 7), and can perform recording of work.

[0028] Fig. 7 shows a recording screen which is called when "vertical ascension pipe" is selected on the work record input menu screen in Fig. 6. On the recording screen of the PDA terminal 2, an inspection/repair specification 71, target oven and kiln 72, an operation date 73, and a comment 74 can be input. Further, a damage degree 75, an illustration 76, and a list of damage degrees 77 can be selected and input. A deterioration degree regarding a portion, among the respective portions of the oven body, in which damage occurred therein directly influences a life of the oven body is evaluated as a digitized damage degree. The digitization of damage degree can be objectively performed by appropriately selecting from levels of damage degree which are previously defined in a selectable manner for digitizing a visual evaluation result of the worker. For instance, regarding the "vertical ascension pipe" shown in Fig. 7, levels of damage degree are defined in a selectable manner such that "presence of hole" corresponds to 5 points, "presence of crack and ignition" corresponds to 4 points, and "presence of crack and gas leak" corresponds to 3 points. Meanwhile, a deterioration degree regarding a portion whose damage, if occurred therein, does not influence the life of the oven body almost at all is evaluated with "presence of damage" and "absence of damage".

[0029] Hereinafter, each processing conducted by each unit of the information processor lb of the oven body management server 1 shown in Fig. 2 will be explained.
(Oven body record information editing processing) The wall surface management information 4 input from the electronic pen 3 and the oven body management information 5 input from the PDA terminal 2 are processed in the information processor lb of the oven body management server 1 through a predetermined calculation flow. The calculation flow edits the wall surface management information 4 and the oven body management information 5 as the later-described oven body record information 6.

[0030] (Periodic inspection priority specifying processing)
The inspection of coke oven is performed for each kiln at every set inspection cycle. In the present embodiment, the wall surface management information 4 input from the electronic pen 3 and the oven body management information 5 input from the PDA terminal 2 are processed in the information processor lb of the oven body management server 1 through a predetermined calculation flow. The calculation flow specifies a priority of inspection work on a kiln-by-kiln basis, based on inspection dates included in the wall surface management information 4 and the oven body management information 5 and periodic inspection cycle information included in oven body basic information 11 previously stored in the storage section 1c of the oven body management server. Further, based on the wall surface management information 4 and the oven body management information 5, a portion with high damage degree among the 21 portions of the oven body of the kiln, is specified as a preferential inspection portion.

[0031] (Repair priority specifying processing)
The inspection of coke oven is performed for each kiln. In the present embodiment, the wall surface management information 4 input from the electronic pen 3 and the oven body management information 5 input from the PDA terminal 2 are processed in the information processor lb of the oven body management server 1 through a predetermined calculation flow. The calculation flow evaluates a value as a result of integrating the damage degrees of the respective portions included in the wall surface management information 4 and the oven body management information 5 as a comprehensive damage degree of each kiln, and specifies, based on the comprehensive damage degree, the priority of repair work on a kiln-by-kiln basis. Further, based on the wall surface management information 4 and the oven body management information 5, a portion with high damage degree among the 21 portions of the oven body of the kiln is specified as a preferential repair portion.

[0032] (Repair life evaluating processing)
The wall surface management information 4 input from the electronic pen 3 and the oven body management information 5 input from the PDA terminal 2 are processed in the information processor lb of the oven body management server 1 through a predetermined calculation flow. The calculation flow quantitatively analyzes a durability of each repair effect, based on repair dates and the damage degrees included in the wall surface management information 4 and the oven body management information 5.

[0033] (Preventive maintenance repair priority specifying processing)
The wall surface management information 4 input from the electronic pen 3 and the oven body management information 5 input from the PDA terminal 2 are processed in the information processor lb of the oven body management server 1 through a predetermined calculation flow. The calculation flow specifies, based on the repair dates included in the wall surface management information 4 and the oven body management information 5 and the repair life evaluation information 9 obtained by the aforementioned repair life evaluating processing, a priority of preventive maintenance repair work on a kiln-by-kiln basis. Further, based on the wall surface management information 4, the oven body management information 5, and the repair life evaluation information 9, a portion with high damage degree among the 21 portions of the oven body of the kiln is specified as a preferential preventive maintenance repair portion.

[0034] Hereinafter, explanation will be made on inspection and repair management guideline data of the coke oven body (the oven body record information 6, the periodic inspection guidance information 7, the repair kiln guidance information 8, the repair life evaluation information 9 and the preventive maintenance guidance information 10) stored in the storage section 1c of the oven body management server 1. These respective pieces of information can be output to the screen of the PDA terminal 2 to be checked by inspection and repair workers of coke oven on the site of work, for example. Further, it is possible that the other people involved in the management of coke oven output the pieces of information to the screens of PC terminals 12 of their own to utilize the information for each purpose.

[0035] (Oven body record information 6)
The information edited by the aforementioned oven body record information editing processing is stored in the storage section 1c of the oven body management server 1 as the oven body record information 6. Fig. 8 shows an example of screen to which the oven body record information 6 is output. The oven body record information 6 represents past inspection results for each kiln, and is a list of inspection date, result, evaluation and the like of each of the 21 target portions. It is also possible to display detailed data of an item selected from the oven body record information 6 on the screen. For example, if the coking chamber wall (17) is selected from the oven body record information 6, it is possible to refer to image data of wall surface, as shown in Fig. 9. Further, when there exist a plurality of inspection and repair records regarding the same portion in the

past, it is also possible to display the records retroactively in the order of cases. Therefore, it is possible to reduce the labor which has been conventionally required for the recording, management and inspection of the voluminous work records.

[0036] (Periodic inspection guidance information 7)
The information regarding the priority of inspection work specified on a kiln-by-kiln basis by the aforementioned inspection priority specifying processing and the preferential inspection portion of the kiln is stored in the storage section 1c of the oven body management server 1 as the periodic inspection guidance information 7. Fig. 10 shows an example of screen to which the periodic inspection guidance information 7 is output. On the screen to which the periodic inspection guidance information 7 is output, the priority of inspection work specified on a kiln-by-kiln basis and the preferential inspection portion of the kiln are listed. The inspection worker can perform inspection work while outputting the information to the PDA terminal 2, resulting in that missed inspection and inspection error can be effectively prevented. Further, for example, it is also possible to perform display with different colors in accordance with the number of days of inspection delay, to thereby call attention.

[0037] (Repair kiln guidance information 8)
The information regarding the priority of repair work specified on a kiln-by-kiln basis by the aforementioned repair priority specifying processing and the preferential repair portion of the kiln is stored in the storage section 1c of the oven body management server 1 as the repair kiln guidance information 8. Fig. 11 shows an example of screen to which the repair kiln guidance information 8 is output. On the screen to which the repair kiln guidance information 8 is output, the priority of repair work specified on a kiln-by-kiln basis and the preferential repair portion of the kiln are listed. The repair worker can perform repair work while outputting the information to the PDA terminal 2, resulting in that appropriate repair work can be efficiently conducted. Further, for example, it is also possible to perform display with different colors in accordance with urgency and the number of days of repair delay, to thereby call attention.

[0038] (Repair life evaluation information 9)
The repair life evaluation information 9 specified by the aforementioned repair life evaluating processing is stored in the storage section 1c of the oven body management server 1. Fig. 12 shows an example of screen to which the repair life evaluation information 9 is output.

[0039] (Preventive maintenance guidance information 10)
The information regarding the priority of preventive maintenance repair specified on a kiln-by-kiln basis by the aforementioned preventive maintenance repair priority specifying processing and the preferential preventive maintenance repair portion of the kiln is stored in the storage section 1c of the oven body management server 1 as the preventive maintenance guidance information 10. Fig. 13 shows an example of screen to which the preventive maintenance guidance information 10 is output. By performing preventive maintenance repair in accordance with the preventive maintenance guidance information, a trouble occurred to the aged oven body can be avoided in advance. Accordingly, it becomes possible to stabilize the operation of coke oven, prevent the progress of deterioration of oven body, and to prolong the life of oven body.

[0040] As described above, by providing a structure such that the data obtained as the inspection and repair information of coke oven is stored as the information such as the periodic inspection guidance information 7 and the repair kiln guidance information 8, it becomes possible to avoid the missed inspection and inspection delay which have conventionally occurred at the time of inspection work of the coke oven body.

[0041] Further, by providing a structure such that the data obtained as the inspection and repair information of coke oven is stored as the oven body record information 6, it becomes possible to reduce the labor and time which have been conventionally required for the recording, management and inspection of the voluminous work records.

[0042] Further, at the time of determining the priorities of the inspection work and the repair work, the comprehensive consideration is given to not only the deterioration of inner wall brick but also the deterioration of the other portions (predetermined portions other than the wall surface) of the coke oven body, so that it becomes possible to appropriately and concretely determine the priorities.

[0043] Further, by providing a structure such that the data obtained as the inspection and repair information of coke oven is stored as the repair life evaluation information 9 and the preventive maintenance guidance information 10, the trouble occurred to the aged oven body can be avoided in advance, resulting in that it becomes possible to stabilize the operation of coke oven, prevent the progress of deterioration of oven body, and to prolong the life of oven body.
